shardik1 Posted September 9, 2010 Report Share Posted September 9, 2010 Is there an electronmic component, say a digital humidity sensor, that i can use to build a portable weather station? Maybe something compatible with the PICAXE series microcontroller? Quote Link to comment Share on other sites More sharing options...
Hero999 Posted September 9, 2010 Report Share Posted September 9, 2010 Have you checked out the usual suppliers ie. RS Components, Farnell, Digikey, Newark and Jaycar?Yes, it's possible, there are many humidity sensors on the market. Normally they have a capacitance which varies depending on the humidity but it should be pretty easy to build an oscillator and monitor the frequency with a PIC.
